Specification of Letters Patent.

Patented June 18, 1918.

Application tiled June 14, 1815. Serial No. 33.857.

T o all 'whom it may concern:

yBeit known that I, RALH R. Roo'r, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Connectors, of which the following is a full, clear, and exact description. g,

This invention relatesto an electric connector. The object of the invention is to provide a connector more particularly adapted for use in connection with certain parts of the.lighting circuit on an automobile, whereby an external circuit may be intro duced into the usual circuit, which external circuit may contain a lamp or other elec trical device.

Generally speaking, the invention comprises the elements and combinations thereof setforthjn the accompanying claims.

'Reference should be had to th'e accompanying drawings forming a part of this specification, in which Figure l is a side elevation showing the manner of use of the -partoularly designed for use4 in connector in the lighting circuit of an auto mobile, end illustrating one use. to Which the external -circuit may be put; Fig. 2 is a sectional elevation of the connector; F ig. 3 is What may be termed a front elevation of the connector; and Fig. 4 is a rear elevation of the connector.

The connector herein described is particularly designed for the purpose of enabling a trouble lamp or handy lamp to be con nected in the lighting circuit upon an automobile. Some makers of automobiles provide a socket adapted to receive a plug forming the terminal of a circuit which 1s espe# cially adapted to accommodate a handy lamp or trouble lamp, but for the most part auto-l mobile manufacturers do notv rovide any means for using this device. onsequentl if such a device be used on an automobi e it must be inserted in the circuit at some point which is accessible and convenient.

Many for lighting lamps of the automobile which is known as the one-Wire circuit, thatI is to say, eachof the ylamp socketsu on' one side 1s rounded tothe frame of t e vehicle, which forms the returnpath for the current, the current being introduced into the lamps Iby means of a single wire The connector of this invention is mpre connection with such a one-wire system` and when of the automobiles havea circuit` used as hereinafter set forth it eliminates the necessity for removing a lamp from the headlight or other light, and the insertion of a yplug of the ordinary socket, as would ben the case under usual circumstances. While, of course, it is perfectly possible to remove the lamp from a headlight and insert a socket, such a procedure necessitates removal and care of the lamp while removed, and, furthermore, it requires that the front 'part of the headlight be removed while thc plug is inserted.

liy the use of the connector of this uppli 'cation it is unnecessary to remove thc lamp from the headlight, or, in fact, to open the headlight at all.

In the drawing, l represents a headlight which is adapted to house a lamp, it being understood that this Iheadlight is of the one-wire system type heretofore described. At 2 is represented the cable by whichv electricity is introduced to the lamp, it being understood that one side of the lamp is grounded so that the return circuit is through the frame. 3 represents a usual plug used in connection with such lighting circuit/s, and 4 is the socket into which thc plug 3 is 'normally secured. At 5 is generally represented the connector by which current through an external circuit generally represented at 6 is established. l have shown a trouble lamp as the electrical device energized by this external circuit. trouble lamp comprises an electric light`7 carriedby a reector and support 8. 1n the `particular instance there is provided a base 9 within which isa coil, so as. to make the base in effect an electro-magnet, so that when the base 9 is energized the base may be set against any iron part of the vehicle and will be held in place by the magnetic field in a manner which Will'be Well understood. At the same tune the lamp 7 1s receiving current so that the lumpis lighted.

The connector forming the subject matterof this application comprises a casing 10, having an arm ll. The arm l1 has two projecting lugs 12, so that it may be inserted and held in a socket of the usual construction. rlhe casing 10 is provided with right angle slots 13, which are of usual form to receive a plug. For purposes of reinforcing This the interior portion of the nrm 1l I have shown a plug 14 made of insulating material. Within the casing l() there is abody 15 of insulating material. This insulating mw cup-.shaped depression 20 and a recess 21.

of securing the Into the cup-shaped depression 20 extends a conductor 22 and the skinned end of the conductor extends into the recess 21. The element 16 is provided with an opening adapted to receive a screw 23 which is adapted to engage the end of the conductor 22 to hold the same. The screw 20 extends through an opening 24 in the body 15.

The conductor 2G, which together with the conductor 22 forms the two sides of an external circuit, is provided with a head 27. Thron h the head there extends a screw 28. T is screw cooperates with an opening formed in the casin 10 and in the body 15, the screw 28 serving the double purpose head 27 to the casing 10 and holding the body 15 with respect to the casing 10.

When the connector is used the plug 3 is removed from its socket 4, the arm 11 of the` connector is inserted in the socket 4 while the plug 3 is inserted in the casing 1() in the manner illustrated in the drawings. It will thus be clear that under these circumstances a circuit through the lamp 7 will have been established. If we conceive that current is being supplied through the conductor 2, the current will pass to the houd 17, element 16 and conductor 22' to the device inserted in the external circuit,

r thence to the conductor 26 and to the cas- 60 which is herein described, I do not wish to limit myself to its use entirely in this connection, as there are undoubtedly other uses ,to which the connector may be put with equal facility.

Having described my invention, I claim:

1. A connector comprisin a sleeve-like body portion having socket s ots in one end thereof, an extension from said body portion `provided with projections which are adapted to cooperate with a socket, a body of insulating '.nutcrial within the body portion, a terminal melnbel'extending through said body of insulating material, means for securing a conductor to the terminal, and means for connecting a second terminal to the body portion, and in electrical connec tion with the extension before mentioned.

2. A connector comprisin a body portion with a part thereof forme as a sockensaid connector having another portion formed as a plug, a body of insulating material toi-ming part of the connector, a terminal mem ber mounted in said body of insulating material, the terminal member extending ad ,jacent the socket portion of the connector, means for securing a conductor to said terminal member, and uieans for securing a terminal member upon the connector and in electrical connection with the plug portion thereof.

3. A connector comprising a body portion of metal and an extending arm of metal, the said arm heilig `provided with projections which are adapted as a plug, a portion oi' the body end of the connector being formed with the slots which adapt it to act as a socket7 insulating material within the body portion, a connector extending through thc insulating material, said connector coperating with the socket portion of the body portion, means for connecting a conductor to the terminal member, and means for connecting a conductor tothe body portion and in electrical connection with the said arm.

In testimony whereof, l hereunto aiiix my signature in l 1e presence ot' two witnesses.
